Decline of 137Cs in marine foods Marine environment The Committee reviewed the movement of radioactive material released as a result of the accident into the marine environment. By 2012, the concentrations of 137Cs, in the coastal waters off the FDNPS site, were little above the levels prevailing before the accident. Concentrations of 137Cs in marine foods have declined rapidly: 41 per cent of samples caught off the coast of Fukushima Prefecture in 2011 exceeded the long-term limit established by the Government of Japan, decreasing to 17 per cent in 2012, and, from the beginning of 2015, to just four samples out of 9,000 (0.05 per cent). % 41% 17% 0.05% Year 2011 2012 2015 Terrestrial and freshwater environments A large body of Japan-specific information has been accumulated on the levels and transfer of radionuclides released into the atmosphere through terrestrial and freshwater environments. Monitoring programmes that began immediately after the accident enabled timely restrictions to be applied to prevent foodstuffs being marketed where the radionuclide concentration exceeded regulation values and limits established by the Government of Japan. Radionuclide concentrations in most monitored foodstuffs declined rapidly following the accident. Since 2015, no samples of livestock or crop products, and less than a few per cent of most monitored wild food and freshwater fish products, have exceeded the limit established by the Government of Japan. In addition, a small number of monitored agricultural food samples (less than a few per cent) exceeded the Codex Alimentarius guideline levels for international trade in 2011, and no samples have exceeded them from 2012 onwards. The large-scale remediation projects implemented by the national Government of Japan and municipal administrations, as well as natural processes and radioactive decay, have further reduced concentrations of radiocaesium in terrestrial and freshwater environments. No agricultural samples reported exceeded the guideline levels for international trade from 2012 onwards. 141 415 341* AER JA本営1号 Rice monitoring For HANDT EYE 36 ふくしま JAみちのく安達 P ふくしま JAみ50%安定 34 グループ 34
